Description

  The present invention relates to a work instruction creation system that creates a member placement work instruction on a printed wiring board.

  Conventionally, there is a printed circuit board (PCB) as an important item indispensable for an electronic device. A printed circuit board is a circuit board in which a circuit for electronic equipment is transferred to a laminated board in which a copper foil is bonded to an insulator and etched to form a required electronic circuit. It is called a single-sided, double-sided, or multilayer printed wiring board depending on whether there are three or more layers including layers and front and back.

  The mounting of components on a printed wiring board is roughly classified into an insertion mounting method and a surface mounting method. In the insertion mounting method, a component terminal is inserted into a through hole of a printed wiring board, and is soldered and fixed on a solder surface opposite to the component surface. At this time, a heat-resistant coating material called a solder resist is formed in advance on the surface of the printed wiring board so that the solder does not adhere to lands, conductor patterns, or the like other than the lands necessary for soldering.

  In addition, as soldering at this time, there are a method in which component terminals are soldered one by one directly by hand, and a method in which soldering is performed at once by immersing the component terminals in a solder dip tank. On the other hand, the surface mounting method is to apply cream solder to the land of the surface mount component, attach the surface mount component on it, and then heat and melt the cream solder, thereby surface mount component on the land of the printed wiring board surface Solder the terminal. The soldering at this time is called reflow soldering.

By the way, the process until components are mounted on such a printed wiring board is as follows.
(1) Circuit design process: A circuit is designed.
(2) Substrate design process: Designs the layout of the substrate.
(3) Production design process: Designs a method for attaching parts and orders a jig.
(4) Jig design process: Design a jig according to the part.
(5) Manufacturing management process: A work instruction sheet for instructing the mounting work is created.
(6) Installation work process: Parts are installed based on the work instruction.

  Here, in the manufacturing management step (5), a work instruction sheet is created according to the number of workers using commercially available application software, and a work instruction sheet as shown in FIG. 8 is printed out. As shown in FIG. 9, this printed work instruction is placed in front of each worker in a transparent file case or the like. Do.

  FIG. 8 shows an example of a work instruction sheet created in the manufacturing management process. The left side of FIG. 8 shows a board layout and a component layout diagram, and the right side of FIG. FIG. 9 is a diagram showing a work situation of a conventional worker.

  However, since there are a plurality of types of printed wiring boards in the conventional actual work, there are problems as described below. That is, in the manufacturing management process, a work instruction must be prepared for each type of printed wiring board to be worked, and even for a single printed wiring board, the operator who actually installs the component Since it is necessary to create work instructions according to the number, there is a problem in that a huge amount of work instructions must be created and stocked in the manufacturing management process.

  Further, in the attachment work process (6), the work is divided in a state in which the number of workers is determined in advance, and there is a problem as described below. That is, for example, if one of the workers is resting due to a cold at a work site that is set to work by three people, the three work instructions that have been prepared will be useless. In the management process, there is a problem in that it is necessary to create a work instruction for a new work by two people.

Furthermore, at the actual work site in the installation work process, since information on the work skills of each worker can only be obtained about the years of work experience, it is difficult to grasp the precise work skills of individual workers, Due to the difference in work skills, there was a problem that in the installation work process, the idle time of the person who was able to work quickly increased, resulting in a deterioration in manufacturing efficiency.
None

  The first object to be solved is to provide a work instruction creating system that reduces the labor for creating work instructions in the manufacturing management process. A second object is to provide a work instruction creation system that collects information for grasping the skill of an operator.

  In order to achieve the above object, the work instruction document creation system of the present invention generates a layout image GL of a printed wiring board based on board layout information DL on a desired printed wiring board as shown in FIG. Generation unit 2 and component arrangement pattern image generation unit that generates component arrangement pattern image GP on layout image GL generated in layout image generation unit 2 based on position information DP of the component to be arranged on the printed wiring board 3 and the component arrangement pattern image GP generated in the component arrangement pattern image generation means 3 based on the component allocation information DW for allocating the component arrangement to the worker, for example, by changing the color or line type. The component arrangement pattern dividing unit 4 and the component arrangement pattern dividing unit 4 divide the pieces in an identifiable manner. For each unit, and configured with the generated image and the image output means 5 for composite output.

  Here, the component arrangement pattern dividing unit 4 divides the component arrangement pattern image GP based on division unit number information set in advance, or the component arrangement based on predetermined worker information set in advance. It is preferable to divide the pattern image GP. In this case, it is effective to exclude the member arrangement pattern image GP in the same part based on the part information. Moreover, it is preferable to change the allocation of the component arrangement pattern image once divided and set based on the external input information.

  Further, work information for starting the image output by the image output means 5 based on the start input process before the work start, recording the work start information, and recording the work end information based on the end input process after the work ends. It is preferable to provide the recording means 6. In this case, it is effective to use the information recorded by the work information recording means 6 for part or review of the worker information.

  In order to achieve the above object, a work instruction document creation program according to the present invention includes a layout image generation step for generating a layout image of a printed wiring board based on board layout information on a desired printed wiring board, and a printed wiring board. A component placement pattern image generation step for generating a component placement pattern image on the layout image generated by the layout image generation means based on the position information of the component to be placed, and for assigning the placement of the component to the operator A component placement pattern dividing step for distinguishably dividing the component placement pattern image generated in the component placement pattern image generating step based on the component allocation information, and an image generated for each unit divided by the component placement pattern splitting step Image output step They are out.

  That is, the work instruction document creation system of the present invention can be easily realized by causing a computer device or the like to read a program recording the above steps and executing a series of processes. In this case, when the program is in the form of a program recording medium, production, sales, distribution, etc. can be easily performed as a software product independent of the apparatus. Also, the work instruction creation system according to the present invention can be easily implemented by incorporating this software in hardware such as a computer device in advance.

  The work instruction creation system according to the present invention can easily divide a part arrangement pattern simply by changing part assignment information for assigning parts to a worker. Labor can be greatly reduced.

  Further, since the work information of the worker is recorded by operating the system, it is possible to easily collect information for grasping the skill of the worker.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing an overall outline of a work instruction creation system according to the present invention.

  The work instruction creation system 1 is configured by a network computer system or the like, and is roughly divided into a layout image generation unit 2, a component arrangement pattern image generation unit 3, a component arrangement pattern division unit 4, an image output unit 5, and a work information recording unit 6. It has.

  The layout image generation means 2 generates a layout image GL of a printed wiring board based on the board layout information DL on a desired printed wiring board. The board layout information DL is determined in the circuit design process and the board design process. Use the information as it is. The component arrangement pattern image generation unit 3 generates the component arrangement pattern image GP on the layout image GL generated by the layout image generation unit 2 based on the position information DP of the component to be arranged on the printed circuit board. The part position information DP uses information determined in the production design process as it is.

  The component arrangement pattern dividing unit 4 generates the component arrangement pattern image GP generated by the component arrangement pattern image generation unit 3 based on the component allocation information DW for allocating the component arrangement to the worker, for example, the color and line type. The component allocation information DW is information determined in the manufacturing management process. The component allocation information DW includes, for example, division unit number information that is information on the number of installation workers, and worker information that indicates the skills of the installation workers.

  The image output means 5 synthesizes and outputs the generated image for each unit divided by the component arrangement pattern dividing means 4 to, for example, a liquid crystal display device. The display image itself displayed on the liquid crystal display device is This is a work instruction in this embodiment. The work information recording means 6 records a start input process before starting work and an end input process after finishing work, and controls the image displayed by the image output means 5. Specifically, the start input process before the start of work and the end input process after the end of work in this embodiment are all performed by bar code input, and by checking on the system side that desired information has been input, Predetermined processing is performed.

  As described above, there are circuit design processes, board design processes, production design processes, jig design processes, manufacturing management processes, and mounting work processes as processes until components are mounted on the printed wiring board. Among the processes, in the jig design process, among the necessary information for carrying out the present invention, the board layout information DL on the printed wiring board and the position information of the parts to be arranged on the printed wiring board Will have DP. Moreover, in the manufacturing management process in the next process of the jig design process, the part allocation information DW is included among the necessary information for carrying out the present invention.

  Therefore, in this embodiment, a system is disclosed in which a work instruction can be easily created simply by inputting necessary minimum information in the manufacturing management process in the jig setting process so that it can be most easily implemented in the work process. That is, in this embodiment, the information necessary for creating the work instruction is divided into “substrate layout information DL + component position information DP” and “component allocation information DW”, and the “substrate layout” obtained when undertaking jig design. The system is constructed from the “information DL + part position information DP”, and the “part assignment information DW” is input as a parameter to complete the work instruction. Thereby, it becomes possible to flexibly change the work instruction according to the actual condition of the production line.

  In addition, it cannot be overemphasized that the work instruction document preparation system 1 in this embodiment can be constructed in any process as long as it has necessary information. In this embodiment, the component allocation information DW not only divides the component arrangement pattern in consideration of the division unit number information which is the number information of the installation workers, but also worker information indicating the skills of the installation workers. The component arrangement pattern is also divided by considering the above. The main purpose of this is to improve work efficiency. Furthermore, as a rule set in advance, the same parts are arranged by a single installation worker. This is a measure for reducing misplacement of members.

  Next, the operation of this embodiment will be described. This work instruction document creation system 1 includes five function blocks: (1) work division function, (2) work pattern instruction function, (3) line display function, (4) management function, and (5) data maintenance function. With these functions, the functions of the layout image generating means 2, the component arrangement pattern image generating means 3, the component arrangement pattern dividing means 4, the image output means 5, and the work information recording means 6 are realized. Yes.

  (1) The work division function performs allocation processing of components to be attached for each work line, (a) reading of printed wiring board data, (b) copy of work division job, (c) work division. Each function includes job editing and (d) work division job deletion. (2) The work pattern instruction function is for selecting and instructing the number of attachment workers from one person, two persons, and three persons for each line.

  (3) The display function for the line displays the start / end of work input, the parts box confirmation instruction display, the work instruction display, etc. on the liquid crystal display device arranged in front of the installation worker on the line. It is. (4) The management function is for displaying or printing a work history recorded based on information obtained from work start / end input and confirming the work history. (5) The data maintenance function is a maintenance function such as parts code table maintenance, installation worker information maintenance, and line information maintenance.

  2 to 7 are diagrams for explaining an operation example of the work instruction creation system according to the present invention, FIG. 2 is a flowchart showing an operation procedure of the work instruction creation system, and FIGS. 3 to 7 are display devices. It is an example of an assist display screen displayed on the top.

  First, it is determined whether or not an existing work division job is to be used (S101), and if not used (S101; N), the “board layout information” of the printed wiring board obtained via an e-mail or other information transmission path DL + component position information DP "is read and a new work division job is created (S102). On the other hand, in the determination process in step S101, when an existing work division job is used (S101; Y), the existing work job is read (S103). An existing work division job can be created by copying an arbitrary work division job, while an unnecessary work division job can be easily deleted.

  Next, as shown in FIG. 3, a work division job editing process is performed (S104). In this work division job editing process, first, a work pattern for selectively inputting how many people work is input (S1041). In the present embodiment, as described above, a selection instruction is given from one person, two persons, and three persons. In the following description, it is assumed that three people are selected in the work pattern input.

  When three people are selected, a division process that seems to be optimal for the line is performed in accordance with the above-described conditions. Specifically, when the types of parts are the same or similar, and when the number of parts is divided by 3 which is the number of workers in this case, based on information such as the location and number of the parts, the same member is Temporary division processing is performed based on the setting rule that no division is performed or that where the arrangement locations are close is not divided as much as possible (S1042).

  Subsequently, the re-division process is performed manually while viewing the layout display subjected to the temporary division process (S1043). This is to make it possible to easily correct a portion that has not been successfully divided only by the setting rule. If there is no correction point in the division in the provisional division processing, it can be passed as it is. In addition, here, an example is described in which division processing is automatically performed by provisional division processing, but first, a line is selected by selecting a part number on the layout screen after selecting a desired line. It is also possible to assign work individually for each. The selected order becomes the work order as it is.

  When the division processing is completed, it is possible to add and edit a comment such as a note or assign a barcode to a job, and then record the edited data by performing a storage process (S1044). This is the end of the process in the manufacturing management process.

  Next, the process in the attachment work process in a line is demonstrated. On the line side, first, the work pattern for today is selected and input by the installation worker. Here, three people are selected. The line name is registered in the maintenance of the line information. A bar code table as shown in FIG. 4 is prepared on the line side. When a work pattern is input here, a necessary input request is displayed on the liquid crystal display device. Enter the input items using a barcode scanner.

  As an example of input items, as shown in FIG. Worker name, 2. Line, 3. Substrate, 4. Error reset, 5. When there is an input of a part or the like and this bar code data is input at the start of work, matching processing is performed to determine whether the part matches the display content. This prevents a component selection error due to a human error of the installation operator. When these input processes are correctly performed, as shown in FIG. 5, a pattern image of the printed wiring board is displayed, and the work performed by the attachment worker is displayed on the liquid crystal display device. Here, the working environment in the present embodiment shown in FIG. 5 is substantially the same as the conventional working environment shown in FIG.

  Each function such as a management function and a data maintenance function checks a work log as shown in FIG. 6 or performs maintenance in a screen showing a part code table, worker information, and line information as shown in FIG. can do. The order in which barcodes are input by the installation operator can be changed in a timely manner in the processing flow, and input items may be added. This is a management function and data maintenance function. The same applies to the items to be performed.

  In the above flow, when a situation where the installation worker suddenly takes a rest due to a cold occurs, conventionally, it was necessary to return to the manufacturing management process and re-create the work instruction. However, in this embodiment, when inputting today's work pattern, a work instruction for automatically processing by two people is created by selecting and inputting two people and displayed on the liquid crystal display device. The Therefore, it is possible to respond immediately to a sudden change in the work pattern on site, and there is an effect that it is free from troublesomeness.

  In actual work, the skills of the three people are not necessarily uniform, and only one person may be slow. Such a case can be dealt with by reducing the allocation of the corresponding installation workers, but until now it has been difficult to optimize the allocation. In this embodiment, since the start and end of the work are notified to the system by bar code input, based on this input, the work speed (for example, work time, work time) of each workman, and worker information (experience) Habituation, skill data) can be grasped.

  Furthermore, since this data is fed back as information at the time of division processing, appropriate division processing is performed, and as a result, work flow and efficiency are improved. In addition, labor costs per hour for such installation workers have often been set uniformly since there was no way to measure individual capacities, but information for reviewing wage settings individually. Can also be used.

  Thus, in the flow of work using this system, first, information necessary for jig design is sent from the board design department to the jig design department. This information includes the board outline drawing, the part number, the number, the position on the board, and the like. Next, the jig design department designs a jig based on information from the board design department, and passes it to the board design department. The board design department uses the jig to manufacture the board. Here, the jig design department creates “substrate layout information DL + part position information DP” as data and passes it to the manufacturing management department. The “board layout information DL + component position information DP” includes information necessary for the operation of attaching all components.

  The manufacturing management department decides which part of the “board layout information DL + part position information DP” is assigned to which part is to be worked. If you work with three people, make three work instructions. Then, when one of the installation workers in the installation work department rests due to a cold, when the data of “board layout information DL + component position information DP” is reassigned to the remaining two workers, two work instructions Can do. In addition, even if only one of the three installation workers is slow, the information on the installation operator is taken into consideration, so that the assignment of the installation operator is automatically reduced, and the whole As a result, work efficiency can be increased.

  In addition, as an operation example using this system, when this system is constructed as an online instruction system and loaned from the jig design department to the manufacturing management department, in order to prevent accidental malfunctions due to erroneous data, It is also conceivable to operate correctly only with the data of “board layout information DL + component position information DP” set in the tool design department. In this case, the completed work instruction is transmitted to the worker online, and the installation worker calls the instruction with a barcode.

  Further, as described above, the installation operator checks the board and parts by inputting the barcode, and also checks the barcode when the installation is completed. By storing all these bar code inputs (input time), it is possible to optimize the dividing process and check the skill of the installation worker. It goes without saying that the part code can be easily changed so that it can be easily replaced with a compatible part.

  Thus, in this example, conventionally, the on-site person in charge of the production management process is in charge of creating the work split instruction, improving the situation that the efficiency is reduced, shortening the production time of the printed wiring board, There is a remarkable effect of reducing the production cost and thus securing the actual work personnel.

  Also, instead of the conventional paper-based work instructions, the use of a liquid crystal display makes it easy to see the contents of the work even if the work site is somewhat dark, and in combination with easy-to-understand color display and barcode usage, Elimination and clarification of worker roles can be clarified, leading to improved product quality. This quality also has the effect of making it easier for the operator to understand and preventing erroneous insertion of parts, and preventing delays due to delays caused by the trouble of creating a division diagram when the creation frequency is high.

  Furthermore, by performing this process in the jig design process, this system can be provided simultaneously with the creation of the jig, and the work instructions can be obtained in a shorter time and at a lower cost than before. Can be operated efficiently.

  The work instruction document creation system of the present invention has been specifically described above based on the embodiment. However, the present invention is not limited to the above embodiment, and various modifications and changes can be made without departing from the scope of the present invention. Application is possible. For example, the processing method related to the work division process can be arbitrarily changed and modified.

  As a program storage medium used for installing the communication control program in the computer device and making it executable by the computer device, for example, a flexible disk (FD), a CD-ROM (Compact Disk − In addition to package media such as Read Only Memory (DVD) and DVD (Digital Versatile Disk), the program may be realized by a semiconductor memory or a magnetic disk in which a program is temporarily or permanently stored. Further, as means for storing the program in these program storage media, a wired or wireless communication means such as a local area network (LAN), the Internet, a digital communication satellite, etc. may be used, such as a modem or a router. You may make it store via various communication apparatuses.
